Does your home rely on well water? If so, a major component of your water system may be a sediment filter. This is usually a whole house sediment filter but could also be a point-of-use unit.
No filter lasts forever. All sediment filters need to be replaced after long periods of use. However, you can postpone replacing yours by cleaning them regularly.
This guide explains how to clean a sediment filter (both whole house and point-of-use).
Shutting off the water valve to your sediment filter system typically involves turning the valve handle 90 degrees. Instead of being parallel to the pipe, it should be perpendicular.
If your shut-off valve isn’t located immediately before your filter, you may instead shut off your pressure tank by following the water line to it. Shut off power to the water pump if you use one in place of a pressure valve.
There are two basic steps to release pressure in your filter system.
If your sediment filter has an exit valve, close it once all the pressure is released.
Consider placing an empty bucket beneath you as you proceed to this step. It should catch water as it spills throughout the process.
Unscrew the first filter housing after all pressure has been released. This task is easier with a filter housing wrench designed specifically for use with your system. With the wrench, turn the filter housing to the left to unscrew it. Press the button on top of the filter again to release more pressure if it still feels tight.
Remove the cartridge from its housing and pour any water into the bucket beneath you after the housing is unscrewed. Be sure to remove the O-ring with the cartridge.
All you need to clean a whole house sediment filter is a brush, warm water, and soap. Wash the filter housing’s inside and caps thoroughly before rinsing them. Your goal is to remove sediment, mold, algae, etc.
Take this opportunity to examine the O-ring. You might decide it’s best to replace it if it’s in bad condition. Also, clean the O-ring seating. This will ensure it seals correctly.
Now, examine your used filter cartridges to determine if you can reuse them or if they need to be replaced. Even if you’re simply planning on discarding your filter cartridge and installing a new one, take the time to examine it closely anyway.
If the levels of sediment build-up that have accumulated are surprisingly high, this might indicate you need to replace your filter more frequently than you have been. Or, it could indicate you should add an extra step to the filtration process.
To clean and reuse a sediment filter, follow these steps:
Place the O-ring back in its seating for every filter stage. Then, insert the sediment filter cartridge into the filter sump.
Next, screw the housing and filter cartridge into the system module. Use a wrench to tighten.
Reopen the water supply after reinstalling all filter housings. Begin by opening the valve which sends water to the filter. Monitor for leaks during this stage. If you notice any, this might mean an O-ring was installed improperly or it’s damaged. Open the valve at the other end of your water filter if you don’t spot any leaks.
Then, one-by-one, run the water from each faucet in your home. Because the system needs to push air through the pipes, water is likely to be released in bursts or spurts at first.
The water may also initially appear gray or hazy. This is normal. After a few gallons have been used, the filters should be primed and this coloring should go away.
The process of actually cleaning a point-of-use sediment filter is the same as the process described above. However, the process of accessing a point-of-use sediment filter is different.
For example, to access an under-the-sink sediment water filter, you need to:
Again, you can now clean the components according to the instructions for cleaning a whole-house sediment filter. Then, place the clean or new sediment filter back in the housing and screw the housing to the bracket.
Next, open the water valve in the back of the cabinet, then open the tank valve and all filter system lines. Check for leaks and allow the water to run for a few minutes to release air.
Regularly cleaning a sediment water filter can be important for several reasons. They include:
Pay attention to the benefits you enjoy as a result of cleaning a sediment water filter. If you find you need to frequently clean your filter to ensure it works correctly, it’s likely time to simply replace it.
If you have any additional questions on this topic, be sure to ask an expert. Consulting with a pro is the best way to learn more about properly maintaining your water system.
